Steve, I was also fascinated by your comment regarding the yogi. This is something that I have believed for a while - the ability we have to influence the effect upon ourselves of what we eat. My feeling is that probably when we reach that level of awareness, we no longer desire the foods that we previously longed for, but it does mean we could go for a slap up meal with our friends, drink them all under the table and feel fine, which has to be worth doing just once
